New Brunswick has the highest radon levels in Canada. Is your home safe?
One in five homes has levels above the Canadian guidelines.
At Maritime Radon Control, the primary focus is to reduce radon to safe levels in New Brunswick residential and commercial buildings.
We guarantee a 100% success rate reducing radon to safe levels.
What is Radon?
Radon is a radioactive gas formed by the breakdown of uranium in the ground, and can get into your home undetected. You can’t smell it, taste it or see it, but can be detected with special equipment. Radon gas is a leading cause of lung cancer and one in five homes in New Brunswick has elevated levels beyond the Canadian guidelines.
A 2012 Health Canada study found almost 25% of homes tested in New Brunswick were above the recommended levels for radon.
Risk of Exposure
When inhaled, radon gas can irradiate sensitive lung tissue, increasing your risk of lung cancer. The higher the concentrations and the longer the exposure, the higher the risk of cancer.
“Health Canada estimates a non-smoker exposed to elevated levels of radon over a lifetime has a 1 in 20 chance of developing lung cancer. If a smoker is exposed to the same level of radon over a lifetime, the risk increased to a 1 in 3 chance”
MRC offers radon measurement services for short term (48hrs), long term (91 days), and Real Estate Sales (duplicate testing procedures). Our certified measurement providers will follow the guidelines to give you proper results. Radon levels are generally the highest levels in the winter months because the ground pressures and stack effect are at their greatest. We recommend everyone complete a long term test in the lowest livable area in the home October through to April. So remember to test any building where you spend time, as New Brunswick has the highest radon levels in Canada.
Radon enters your home because the pressure in the ground beneath your home is greater than the pressure inside your home. Creating negative pressure in specific areas and using different systems that gather radon and other soil gases before they enter the building envelope and exhausting them outside, is the most effective way of reducing radon concentrations in homes. Our certified mitigation providers have 100% success rate in reducing radon to safe levels.
Active Soil Depressurization Systems (ASD) is the most effective way to reduce radon entry into buildings. They collect soil gases and exhaust them outside to a safe location. However, not all homes are built the same, so each system is determined based on the type of foundation. For example: Sub Slab Depressurization, Sub Membrane Depressurization, Sump/Tile Depressurization, Baseboard Depressurization, Block Wall Depressurization, Crawl Space Depressurization.
Diluting radon levels is another way of lowering concentrations in the home. Increasing fresh air with your heat recovery ventilator (HRV) can help dilute radon gas by small amounts, but it does not stop its entry.
Installing HEPA filters with forced air furnaces allows the negative charged ions to stick to the filter, reducing the amount of air bourne Radon Decay Products in the house. However, this doesn’t stop radon entry into the home.
Real Estate Sales
We recommend a real estate radon test from a certified measurement provider for all real estate sales. Duplicate testing, in closed house conditions with tamper resistant features will give you an accurate indication of the current radon levels for that time frame. Depending on what radon levels the purchaser feel comfortable with, this would give them the option to include a Mitigation system in their offer. All real estate short term tests fall under EPA & Canada guidelines, giving you accurate results for that time. A long term test is recommended by health Canada, but time isn’t an option in real estate sales.
New Home Construction
Every new residential & commercial building should be built with radon resistant features to reduce radon gas exposure. MRC Inspect & Certify Passive Radon Systems for New Construction A properly installed Passive Radon System in new home construction can reduce radon levels up to 52% and still have Energy Efficiency.
